ANTIFRICTION TIP FOR FURNITURE.

Application filed March 9, 1922. Serial No. 542,336.

The invention relates to anti-friction tips for furniture. 1

One ob ect of the invention is to provide an anti-friction tip adaptedto be applied to the legs of pieces of furniture without danger ofsplitting the legs, and which includes a metal head having a smallsurface contact with the floor so that the piece of furniture may bereadily moved by sliding i t over the floor, the contacting face of thehead being curved to prevent injury to the floor.

A further object of the invention is to provide an anti-friction tip forfurniture in which the head is separate from the attaching member and toconnect this member, such as a brad, to the head in such a manner thatthe tip may be driven into the leg of a piece of furniture by blowsdelivered to the head without danger of separating its parts, and sothat the tip may be removed from the leg without danger of separatingits parts.

Vith the above and other objects in view the invention consists in thefurniture tip hereinafter described and all equivalents.

I11 the drawings: Fig. 1 is a section taken on the line 1-1 of Fig. 2;Fig. 2 is a plan view of a tip embodying the invention; Fig. 3 is a viewof the parts making up the tip prior to their connection; Fig. 4: is aview similar to Fig. 1 showing a slightly iuodi tied form of headconstruction for the tip; Fig. 5 is a perspective view of theti p shownin Fig. t; Fig. 6 is a view similar to Fig. 1 showing a slightlymodified form of head construction for the tip.

The tip comprises a head or [leer-engaging member (3 and an attachingmember 7.

In each form the head men'lbcr (i is of pressed metal formed into acylindrical cup having an annularly extending convex floorengagingportion 8 merging at its outer edge into an annular cylindrical flange 9and at its inner edge into a conical portion. 10, the section ofsmallest diameter of said conical portion merging into a ring portion 11having its opening 12 centered in the head. In addition to the abovenamed parts of the head member 6, the flange 9 may have short spurs 13formed thereon, as shown in. Figs. 4: and 5, or the edge may be formedto provide an annular cutting part 21, as shown in Fig. 6.

The attaching member 7 preferably consists of a brad having a pointedend 14 and a tapered end 15 with a flange 16 adjacent said tapered endforming a head-engaging shoulder 17. it-h this construction the taperedend 15 is forced or driven into the opening 12 and is then upset orriveted to the head member 6 to form a head 18 which is located with nthe depression formed by the conical portion 10. By this constructionbrad 7 has a drive fit on the head and the head 6 is tightly rivetedbetween the shoulder 17 and the shoulder 19 formed by head 18. With thisconnection the tip may be driven into or taken out of the leg of a pieceof furniture without danger of separating the parts, as the pressuresexerted upon the head member in driving are transmitted to the bradthrough the shoulder 17 and the pressures exerted in extracting the tipare resisted by the flanged head 18. The tip may be set or driven intothe furniture by striking the curved annulus 8 with a hammer or othersuitable tool and the tip may be so driven as to embed its flange 9 inthe leg 20 to which it is attached, as shown in Fig. 1. However, topositively relieve the brad of any shearing strains occasioned bystriking the tip against an obstacle when moving the piece of furnitureto which it is attached, the short spurs 13 may be used, or the edgeprovided with the part 21 to rehere the brad of shearing strains. As thetip has but one attaching member and this is located at the center thereis no danger of splitting the leg to which the tip is attached as thereis ample stock from the center to the outer edge of the leg. lVith sucha construction the limited. contact afforded by the annulus 8 with thefloor reduces the frictional engagement between the legs of the piece offurniture and the floor to a minimum so that the article may be readilyshifted about with a minimum of effort.

It will be further noted that by the use of a suitable nail set appliedto the central depressed portion of the tip that it may be driven intothe furniture without the danger of flattening the curved floor-engagingpor-, tion 8 of the tip by repeated blows of a hammer.

What I claim as my invention is:

1. In an anti-friction tip for furniture, the combination of a cupshapedfloor-em gaging member having a recessed central port-ion and an annularfloor-engaging portion, and a brad having spaced cooperative flanges onits head end fixedly clamping it to said recessed central portion out ofcontact with the floor.

2. In an anti-friction tip for furniture, the combination of afloor-engaging member having a eonvexly curved annulus engage able withthe floor and an .aninilar flange portion engragreable with the articleto which the tip is applied, there being a conically formed. centralrecess within said annulus, and fastening means passing through thecentral portion of the floor-engaging member and having its headdisposed in said recess out of contact with the floor.

3. In an anti-friction tip for furniture, the combination oi acup-shaped floor-engaging member having a recessed central portion andan annular floor-engaging portion, and a brad having its head disposedin said recess free of the floor and flanged to engage one side of saidmember and having a cooperative llange engaging the other side oi saidmember.

at. In an anti-friction tip for it'iu'nitlu'e, the combination of afloor-engaging member having: a recessed central portion and an annulartoor-eng agin g portion, and a, brad having a tapered head and aflangeadjacent thereto, said tapered head having" a pressed lit in a centralopening;- in said central portion and having; a part 111 go against saidmember to form a flanged head, said flanged head being disposed. in saidrecessed portion free of the floor.

In testimony whereof, I allix my signature.

FRANK MACEY.
